Abstract
Gaseous contaminants, especially sulfur dioxide, sulfur trioxide, hydrogen chloride or hydrogen fluoride are removed from flue gases by chemisorption. A solid finely divided sorbent, before being brought into contact with the flue gas, is treated in a reactor with dry steam. The sorbent before introduction into the reactor is brought to a temperature of 10 DEG to 50 DEG C. below the dewpoint temperature of the steam in the reactor and the steam injected into the reactor is introduced at a temperature not more than 60 DEG C. above the dewpoint temperature, preferably 10 DEG to 40 DEG C. above the dewpoint temperature.
